    4.7 Q

    In AP Physics 1/2

    Posted

    A 0.15-kilogram baseball moving at 20 m/s is stopped by a catcher in 0.010 seconds. The average force stopping the ball is: 

    (A) 3.0x10^-2 N

    (B) 3.0X10^0 N

    (C) 3.0X10^1 N

    (D) 3.0X10^2 N

     

    The explanation says that it takes 0.010 seconds for the baseball to accelerate from 0 m/s to 20 m/s, but that doesn't really match up with the question... Is the wording a little weird?
